PROTECEIIVE MAT FOR STOVES Filed Aug. 21, 1939 Patented A r-.19, 1940 Y invention'relatesto mats for stoves, and "its'general object' is' to provide a, mat that is' primarily designed-}for protecting enameled or like finishedf'topfs of the ,oven or other parts of -cooking appliances, against becoming cracked, scratched or 0th'ervvise1damagedby I the application ofacdeking vessel thereto, in ,that my mat-not only acts to support the vessel'elevated from the finished surface, but allows for the free circulation of air between the mat andsurface,

- as well as below the vessel, thereby preventing thermal shocks caused by placing a cold vessel upon the heatedsurfaceQwhich generally results in crackingthe finish and in any event discolors the same, but by the'use' of my mat the finish is maintained free from damage. I v v A further object is'to provide a protecting mat for the purpose set forth, that is preferablyv finished with porcelain on steel, and is not only ca- J steel so that the ends thereof are integral'yas that event the sheet will be slit" and pable of protecting-the finish of the stove, but

adds materially to the-appearance of the latter-..

Another object istoprovide a protecting mat that is simple in construction, inexpensive to;

"manufacture, and extremely eflicientin u'seand service, v I

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be herei inafter fully describedillustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the mvention in detail, reference I willbe had to the accompanying drawing where- 1 "section to provide fiat upper walls andstraight in like characters denote like. or' corresponding parts throughout the" several views, and in which:

Figure 1 is a top. plan view of the mat which forms the subject 'matterof the present invention. Y p Figure 2 is a side view, with parts in section.

Figure 3 is asectional view taken approximately on line 3-3 of Figure 1 looking, in the direction of the arrows.

Figure 4 is a sectional inatelyion line 4- of Figure 1.,

Referring to the drawing in noted that 'my mat is constructed substantially in the form of a grate, to include relatively narrow elongated channeled end bars I having the .open porrtions'facing downwardly and the bars are ofv inverted substantially" U-shape .in cross parallel side walls having outwardly flared lower edges; as best shown in Figure 4'. Frictionally fitting within the'channels of the end bars and at the ends thereof are rectangularshaped blocks 7 shown, and in Y shaped to provide the ribs.-

may be formed from individual strips of steel,

From the above description'and disclosure in the drawing, it will be obvious that I have provided a mat that can beset upon an enameled surface of-the top of an'ovenor other'part of a description that the advantages and novel features ofthe invention will be readily apparent.
